- Command execution failure
- Unable to execute command
- Unknown Error Code:- 2147012894
- Unknown Error Code:- 2147012852

## Investigating Problem Causes

The possible reasons of this issue could be:

- **The user doesn't have access to Setup.exe file, and hence won't be able to execute it.**
- **Due to antivirus blocking.**
- **The proxy credentials given in the Proxy Settings are not valid.**

To resolve the issues, follow these steps:

### Step 1:

Allowlist the mentioned domains in this [page](https://learn.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide) in your proxy to download the Office patches.

### Step 2:

If the download fails even when the above-mentioned links are whitelisted, follow the steps mentioned below to ensure that there is no network issue or privilege issue in your environment:

- Login to the server installed system and create a folder named **o365**.
- Copy the XML content mentioned below and save it with the file name as **download.xml**. Place the file in the **o365** folder that you created in the first step.

  **Note**

  ```xml
  <Configuration>
   <Add OfficeClientEdition="64" Channel="Current">
    <Product ID="O365ProPlusRetail">
     <Language ID="en-us"/>
    </Product>
   </Add>
   <Display AcceptEULA="TRUE"/>
  </Configuration>
  ```

- Download the [office deployment tool](https://www.microsoft.com/en-US/download/details.aspx?id=49117) and place it in the **o365** folder along with **download.xml**.
- Then extract the **.exe** file using 7zip in the same path.
- Run Command Prompt as **administrator** and execute the below-mentioned commands:

  **Note**

  ```bash
  setup.exe /download download.xml
  echo %errorlevel%
  ```

- Once the above-mentioned steps have been executed, the error level should be **0**. In case any other value is displayed, kindly [contact support](https://www.manageengine.com/patch-management/support.html).

### Step 3:

Once the above-mentioned steps have been performed and if the **exit code is 0**, then there might be a privilege issue in your environment. To resolve, perform the following steps:

1. Open Run (Windows key + R) > type **services.msc**
2. Right-click on **Patch Manager Plus UEMS - Server** > **Properties**
3. Click on **Log On**
4. Click on **This account**, type in the credentials of the system's admin account and click on **OK**
